Answer:
[tex]a=\sqrt{33}[/tex]
Step-by-step explanation:
The Pythagorean theorem tells you that the area of the square with side 'a' is the difference of the areas of the other two squares.
a² = 7² -4²
a² = 49 -16 = 33
a = √33

The drawing below shows 3 parking lots that enclose a shopping mall shaped like a right triangle. If Lot A’s perimeter is 40 miles and Lot B’s perimeter is 24 miles, what is the perimeter of Lot C?
Answer:
40 miles because they are da same size
Step-by-step explanation:
The perimeter of lot C is 46.64 miles
Lot C is a square, hence the perimeter of lot C with a length of each side as a miles is:
Perimeter = 4 * length = 4a
40 = 4a
a = 10 miles
Lot B is a square, hence the perimeter of lot B with a length of each side as b miles is:
Perimeter = 4 * length = 4b
24 = 4b
b = 6 miles
Let c represent the length of lot A,, since a, b, c form a right angle triangle. Using Pythagoras theorem:
c² = a² + b²
c² = 10² + 6²
c² = 136
c = 11.66 miles
Perimeter of lot C = 4 * c = 4 * 11.66 = 46.64 miles
The perimeter of lot C is 46.64 miles

a water spinkler sends water out in a circular pattern how large is the watered area if the watering pattern is 12 ft
Answer:
The number of feet away from the sprinkler where it could spread water would be the radius of the circle in which it is spraying.
The Area of a circle is
πr2=808.64
(3.14)r2=808.64
Divide both sides by 3.14

Useful Log Rules:
log(A*B) = log(A)+log(B) .......... log rule 1log(A/B) = log(A) - log(B) .......... log rule 2log(A^B) = B*log(A) ................... log rule 3=========================================================
Part (a)
All logs shown below are base 3.
log(500) = log(5*100)
log(500) = log(5*10^2)
log(500) = log(5)+log(10^2) .... use log rule 1
log(500) = log(5) + 2*log(10) .... use log rule 3
log(500) = 1.4650 + 2*2.096 ....... substitution
log(500) = 5.657
Answer: 5.657=========================================================
Part (b)
All logs shown below are base 3.
log(2) = log(10/5)
log(2) = log(10) - log(5) .... use log rule 2
log(2) = 2.096 - 1.4650 ....... substitution
log(2) = 0.631

How old is my uncle if 400 reduced by 2 times his age is 244?
Answer:
My uncle is 78 years old.
Step-by-step explanation:
Let the age of your uncle be x.
400 - 2x = 244
Shift (-2x) to the other side and change it to (+2x).
400 = 244 + 2x
Shift (+244) to the other side and change it to (-244).
400 - 244 = 2x
Evaluate.
2x = 156
Find x.
x = 156 ÷ 2
x = 78

The dance company is choosing 3 new dancers from a group of 25 who try out, how many ways can they choose the new dancers
Answer: 2300
Step-by-step explanation: 25C3
The number of ways of choosing the new dancers is ²⁵C₃ = 2300 ways
What are Combinations?The number of ways of selecting r objects from n unlike objects is given by combinations
ⁿCₓ = n! / ( ( n - x )! x! )
where
n = total number of objects
x = number of choosing objects from the set
Given data ,
Let the number of ways of choosing the new dancers be C
Now , the total number of dancers in the group = 25 dancers
The number of new dancers selected = 3 dancers
And , the number of ways of choosing the new dancers C is calculated by the combination rule ,
where the number of ways of choosing the new dancers be C = ²⁵C₃
On simplifying , we get
²⁵C₃ = ( 25 )! / ( 25 - 3 )! ( 3 )!
²⁵C₃ = ( 25 )! / ( 22 )! ( 3 )!
²⁵C₃ = 25 x 24 x 23 / 3 x 2
²⁵C₃ = 25 x 23 x 4
²⁵C₃ = 2300 ways
Hence , the number of ways of choosing dancers is 2300 ways

Find the measure of angle N.
Answer:
Step-by-step explanation:
The angles of that 5-sided polygon add up to equal 540 degrees. So we add up all the angles and solve for x, then plug x back in to angle N to get our answer.
17x + 4 + 10x - 10 + 18x + 6 + 90 + 90 = 540 and
45x + 180 = 540 and
45x = 360 so
x = 8
Now we'll fill 8 back in for x to get the measure of angle N:
18(8) + 6 = 150, the last option listed
